Abstract
A spectrum analyzer having an automatic attenuator setting function, actuatable to automatically set the degree of attenuation provided by an input attenuator to an optimum value in accordance with the peak level of the frequency span of a signal under measurement, i.e. to a minimum attenuation value consistent with the prevention of generation of spurious signal components through distortion within the spectrum analyzer, e.g. harmonic frequency distortion within the mixer of the spectrum analyzer. Low-level frequency components can thereby be observed without the presence of spurious components on the spectrum analyzer display, with no need for manual input attenuator adjustment. A compensating degree of I.F. amplification is automatically provided to match the attenuation setting.
